摘要
大同含炭硬质高岭土经化学漂白、超细粉碎和煅烧处理,可获得造纸涂布用煅烧高岭土。其主要物化性能达到造纸工业用国标优级高岭土指标。其中化学漂白采用氢还原除铁,效果显著。
Datong coal-series kaolin can be used as paper coating after being processed by chemical blanching, ultra-fine comminution and calcine. All performance index of the obtained product are up to the national standard of quality kaolin for paper-making. In blanching, hydrogen is used as a effective reducing agent for Fe 3+ .
